Will this work for the aquatic life buddie?

Yes it is still working well for my aquatic life ro buddie.

Will this work with hydro logic stealth ro200?

Yes,our 100GPD-2012 size membrane is perfectly compatible with Hydro-logic's Stealth 200 Reverse Osmosis System.

Do any of your ro membranes fit the ao smith ao-us-ro-mb-4000

I am unfamiliar with the system you were referring. However I can offer you this. This is the standard in filtration systems as I know it. If the membrane meaning the RO membrane can fit in a housing that is designed for it then usually that means it will work. So an example would be if you had a 10 inch long 2 1/2 inch diameter housing for a membrane you would roughly need a 10 inch long 2 1/2 inch wide membrane lol. Something helpful for the future as well. Whenever I purchase anything I keep the instruction manual for it in the same place for everything I own. That way if I have a question I can simply go to my “library” and find my answer lol.

Will this work with an ultima vii system?

Your system makes 24gpd, The membrane filter your asking about makes 50gpd. You can upgrade your system to 50gpd by making some changes to the flow restrictor. Go to utube and view numerous videos on RO systmes. The filter will work only after some changes to your system.
